Solution
Verify the AC power cord is plugged into the wall outlet.
Turn the POWER/VOLUME knob clockwise on the back of the BB2001
Powered Subwoofer until you hear a click sound.
Check volume level on the audio source device, and set at mid-level.
Turn the POWER/VOLUME knob clockwise to raise the
subwoofer volume.
Make sure one end of the 3.5mm stereo cable is properly plugged
into the output labeled "SUB OUT" on the back of the primary
speaker system, and the other end is properly plugged into the input
labeled "SUB IN" on the back of the BB2001 Powered Subwoofer.
Many .WAV and .MID files often have little low-frequency content
and sound flat when you listen to them on a computer. Try a song
with more bass — something from your CD collection.
Move the subwoofer until the interference goes away.
Because the subwoofer is not magnetically shielded, it can cause
distortion if it's too close to your monitor. Move the subwoofer so
it's at least 2 feet from your monitor.
Some low hum may be detected when your speaker system is
powered on without an audio source playing, or when the volume
is set at an extremely low level.
Unplug the AC power cord from the surge protector (if used), and
plug directly into an AC wall outlet.
Make sure one end of the 3.5mm stereo cable is properly plugged
into the output labeled "SUB OUT" on the back of the primary
speaker system, and the other end is properly plugged into the input
labeled "SUB IN" on the back of the BB2001 Powered Subwoofer.
Disconnect your 3.5mm stereo cable from the audio source. If the
loud hum goes away, lower the volume on the audio source.
Lower the volume or bass level on your computer, portable device,
etc.
Turn the POWER/VOLUME knob counterclockwise to lower the
subwoofer volume.
